Instruction, Training, Learning Experiences most often cannot account for and address every varied situation.
The higher the stakes (if Extreme) would have us offer much more varied sets of practice with feedback, to help practitioners discover and see patterns within those situations – and we’d even want to point them out in debriefing/reflections – and discuss additional scenarios – and what the appropriate response(s) might be.
For people in High Stakes Performance, such as fire fighters, police, military, nuclear plant operators, etc., there should be a continuous set of “spaced learning” offered to help keep everyone sharp and minimize the Forgetting Curve, as well as develop the kind of expertise that goes well beyond Formal Instruction, where any trial and error learning needed, is guided by and grounded by “extrapolated insights” from prior, similar, experiences.
Instruction – most often – isn’t really expected to cover every last contingency that may be encountered in the Performance Context.
The Miracle on the Hudson comes to mind:
On January 15, 2009, US Airways Flight 1549, an Airbus A320 on a flight from New York City’s LaGuardia Airport to Charlotte, North Carolina, struck a flock of birds shortly after take-off, losing all engine power.
Captain “Sully” Sullenberger explains exactly what happened that day when he successfully landed a plane on the Hudson River. Something not covered in his Formal Training.
